Determine the moment created by the weight of the suspended sign about point O. Dimensions of the sign and the support are shown in the accompanyitlg figure.. The sign is 2 mm thick and is made of aluminum.
Consider a power plant operating on an ideal Rankine cycle without feed water heating. Steam enters the turbine saturated at 1000F at the rate of 5 x10 lbm/H. The turbine exhausts to a surface condenser at 1 psia. The condenser has an overall heat tr..
A heat pump operating at steady state provides 36,000 kJ/hr to maintain the temperature in a building at 22C. The heat pump operates with a coefficient of performance 75% that of a reversible cycle operating between the same thermal reservoirs.
saturated vapor steam at 4 mpa is contained in a 2 m3 insulated vessel. a valve on the top of the tank is opened
Sketch the graphs of both f (t) and the periodic function represented by the series expansion for -2 t 2.
r-22 undergoes a process between two states. the process has an isentropic compressor efficiency of 80. at state 1 the
Consider a velocity field where the x and y components of velocity are given by u=(cy/(x^2 + y^2)) and v= (-cx/(x^2 + y^2)) where C is constant. Calculate the vorticity of the vortex flow
air enters an insulated compressor operating at steady state at 1.05 bar 23 degrees c with a mass flow rate of 1.8 kgs
A mortar fires a projectile across a level field so that the range (R) is maximum and equal to 915 m. Find the time of flight.
A Circular plate having a diameter of 30mm is held perpendicular to an axisymmetric horizontal jet of air having a velocity of 40m/s and a diameter of 80mm as shown in the figure. A hole at the center of the plate results in a discharge jet of air..
